To all 'whom it'm ay concern."

- Be it knownthat I, ROBERT W. Donen,'a

citizen of the United 'States, residing at Omaha,"in the county of Douglas and State of Nebraska, have" invented a new and use- -ful Steam andI-IQ't-Water Dish-Washer of which the following is a specification.

Y The device forming the subject matter of this application is'a dishwasher, and one object of the present invention is to prpvide in a dish .washer,"a slidably mounted h charge member adaptedto be moved long1= tudinally of a dish-holding means such as a tray, to' the end' that water or steiim may "be delivered upon the tray at diiferent po nts intermediate the endso fthetr'ay." 1 p Another objectoftheinvention is to provide adish washer inwhich the cleansing fluid may-be "delivered upon the 'top"'or 20 against the bottom of the d sh holding tray, at any point intermediate'the'ends of the t'ra. 7 ,(\.1'\, .I I.

notherobject oi-the invention is "to provide nov l'means for selectively directing 2.5 steam and hot waterfor afmixture ofsteam and hot water into the constituent arms of The invention aims 'to improve generally 80 type to which the pnesent invention appertains. I ,a' t a With the, above and other objects in view which will appear as 'the description prov ceeds, the invention resides'in' the combina- 35 tion and arrangement of parts and in'the de-' i tails of construction hereinafter described and claimed, it, being understood that changes in theprecise embodiment of the' in: vention herein disclosed can'be made within 40' the-scope of what is claimed without-depart- Q shaped discharge member are located cut off A .lng fromthe spirit of the invention.

In theaccompanying drawing :Figure 1 1s a side elevation depicting a dish washer embodying the present invention, 'certain 45' parts being shown in yertical. section-and other parts appearing in elevation; =Fi g. 2 us across section on the line 2-2 of Fig. '1.

In carrying "out the 'pre'sent" invention I ,a latch 4 on jhelid 2"a'nd;a keeper-5km. the

casing 1-. At one end, adjalcent its bottom, 53' the casingl'is' supplied an ontlett and to enhance the utility of devices of that which may communicate with 'a' sewer'or drain (not shown). The casing- 1 may be 'upheld'upona suitable frame 7 of any desired sort. Located within the casing 1 are brackets 8 upon which rests removably a tray 9 provided with a foraminous'bottom 10, there beingv partitions 11 which'extend transversely of the tray 9 and divide the same into compartments 12, 14.- ,and '15. There may be any number of these compartments, three compartments being shown in the present instance. Located inthe compartment 14 are bail-shaped separators 16, the lower ends of which are pivoted in the 'J-side walls of the tray 9 as shown at 17.

Projecting inwardly from one end wall of =the' casing 1 are tubular guides 18 and upon the outer face of said wall, in'alinement with the guides 18 are packing glands 19;

- The invention' includes a slidably mounted discharge member, the'same comprising an intermediate portion 20 and arms 21 and 22, the arms21 and 22being slidable inthe e guides 18 and in the glands '19.. "The arm 21 lies above the tray 9 and the arm 22 lies below the tray. At its inner endthetubular arm 21 of the dischar e member is equipped with a transverse tu%ular vhead 23 having perforations upon its lower face, these perforations being adapted to discharge downwardly uponlthe tray 9. Attached tov the inner 'end of the'tubular armf22- is a transverse discharge head 24', perforated upon its upper side, as shown at 25*, so asto side pf the casingl and-is provided withanfj 2 operating handle 26. v a y In the'intermediate portion 20, of thefU valves 28 and .29. and between the valves 28 ,and 29 the intermediate portion 20 o' fthe" dischargemeinber is supplied with a nipple v 27 communicating with one end of a flexible 100 ipipe30 which may-be of any-desired length. The pipe 30 communicates with any-suitable means for supplying steam and'hot' waterto thev casing portion of the. dishwasher. As shown in the-,drawings, the pipe30 is con-' 105 "nect'esdwith-a nipple- 31 formed upon a maljh fo1df 32,:the;ends' 33 of which enter "a boilef l manifold 32far'e'va'lv es 36 and37. l i m.

level "in the boiler.

' 26 and thus the discharge heads 23 and 24 may be positioned at difierent points be-,

opposite sides of the nipple 31. The tank-or boiler may be provided with a water gage 38 and with a pressure gage 39.

In practical operation, the u-shapeddischarge member 2122 may he slid horizontally through the medium of the handle tween theends of the dish holding tray 9. Thus, the dishes in the tray 9 will be cleansed by the fluid traversing the arms 21and 22 and the head 23 and 24. When it is desired that the arm 21 shall 'operate alone and shall convey steam to the contents of the tray-9, the valve 29 is closed, the valve 28 is opened, "the valve 37 is closed and the valve 36 is opened. Should the operator desire to amixture of steam and hot water is to be deliver hot water through the arm 21 only,

- the valve 29 is closed, the valve 28 is opened,

the valve 36 is closed and the valve 37 is opened. Should itbe desired to employ the arm 22 only and to pass steam theretbrough, the valve 28 is closed, the valve 29 is opened,

the valve 37 is closed and the valve 36 is opened. When hot water is to be passed- 'throu h the arm 22 only, the valve 28 is close the valve 29 is opened, the valve 36 is closed and the valve 37 is opened. When steam is to traverse both of. the arms 22 and' 21", the valve 28 is opened, the valve 29 is opened, the valve 37 is closed and the valve 36 is gpened Ifhot water is to traverse both-o y opened, the valve 29 is o ened, the valve 36 the a-rms 22 and 21, the valve 28 is is closed, and'thevalve 3. is opened. When delivered throughthe arms 22 and 21,-the

valves 28,29,'36,and 37- are opened. *If a mixture of steam and hot water is to be v 'delivered to'both arms at once.

delivered jthro ugh the arm 21 only, the f valves 36,?37'angl 2 8 areopen'ed and the valve.

1 29is closed. If a mixture of steam and hot ;water is to traverse the arm. 22 only, the 'valves 36, .37 and 29 are opened and the valve 28 is closed. 1 From the foregoing it will'be seen that a -'mixture of-hot-water and steam, steam only or hot water only may be delivered to each of the arms 22 and 21 separately; hot water 'may be delivered to both arms at once; steam may be delivered to both armsat once; and

amixture of steam and-hot water may be The devicervwill operate satisfactorily Without the use ofsoap and the dishes will -dry readily,fwi thout wiping, either byremoving the tr'ay9 from-the casing 1, or by opening the-lid2. I

Flat ware ordinarily is located in'tlie compartmentvl iythe pieces of flat ware beingg: separated by the bails 16. The hollow w tre which is to be cleansed is (placedin the c( m Ypartinent's 12 and 15,311,

is in-- verted therein so as to be washed by the upward flow of fluid proceedingthrofigh the ,lower arm 22 and its discharge head 24.

The casing 1 may be provided with a nip-' ple 100 adapted to receive an outlet pipe 101-, the motion of which is to conduct away the steam generated within the Having thus described the invention, what is claimed is:

1. In a "dishwasher, a casing; a dish holding means therein; a discharge.member-slidable in the casing and including arms located upon opposite sides of the dish holdmg means; a source of steam and hot water supply; and means for directing steam and hot water respectively into the arms selectively.

2. In a dish washer, a casing; a dish holding means therein; a discharge member slid mg means; a source of steam and hot water.

4. In a dish washer, a casing; a dish holding"means therein; a U-shaped pipe including. arms located upon opposite sides of the 'dish holding means, the ipe being slidable in; e casing; valves in t e U-shaped pipe; and. a source of hot waterand steam supply discharginginto the U-shaped pipe between thevalves. r 55 In a dish washer, a casing; a dish holding means therein; a U-shaped pipe including arms located upon opposite sides of the dish holding means, the pipe being slidably mounted inthe casing; a hot water and steam tank; a manifold connecting the" upper and lowerportions of the tank; valves in the manifold; valves in the U-shaped pipe; and a connection between'that portion ofthe U- shaped pipe whichlies between the valves ofsaid pipe, and that portion of the manifold which lies. between the valves-of the manifold.

In testimony that I claim the' foregoingas my own, I have hereto aflixed my signature in the presence of two witnesses.
